Coils are measured in quarter increments. The lower the number, the thicker the spring. In general, higher-quality mattress coils have a 14-gauge (1.63 mm) diameter. Coils of 14 to 15.5-gauge (1.63 to 1.37 mm) give more easily under pressure, while a 12.5-gauge (1.94 mm) coil, the thickest typically available, feels quite firm.
The "hospital bed" is also a common unit of measurement for the capacity of any type of inpatient medical facility, though it is just as common to shorten the term to "bed" in that usage (e.g. The hospital has 250 beds...).

A standard metric (concrete) block is 190 mm wide, 390 mm long, and 190 mm high, which allows for 10 mm mortar joints in between bricks, giving a standard unit size of 200 mm square by 400 mm long. [3] A standard metric brick is 90 by 57 by 190 mm; with 10 mm of mortar, that produces a standard unit of 100 mm x 200 mm. [3]
Before the establishment of the decimal metric system in France during the French Revolution in the late 18th century, [4] many units of length were based on parts of the human body.
